Why used ac over dc in train?
ac transmits the voltage over long distances. so v use ac in trains
Which current is better ac or dc?
DC is more powerful, the actual ratio is 1.732AC=DC
What is the difference between ac and dc grounding?
The difference AC and DC grounding is that AC is alternate current and DC is direct current. Grounding for both AC and DC is the same.
What is the sign for ac and DC current?
AC means alternating current DC means direct current there is no polarity reversal
What is the different between ac dc motors?
DC Motor works on DC source and AC motor works on AC source
What are the advantages of DC to ac inverter?
Dc invereters are not well suited as compared to ac inverters.This is due to the reason because ac inverters are more efficient ,less dangerous and good for supply over distance.
What are the advantages of DC over AC in extraction of copper?
DC is necessary in the electrolytic process to refine copper. In other processes for extracting the metal from the ore, where heat is needed, AC is preferred because it is more easily transmitted over distances.
Advantages of Ac to DC converter?
some things requre a dc (direct current) rather than an ac (alternating current)
What is the advantages of the universal motors?
the universel motor can runs at both ac and dc supply.
What are the advantages of using a DC motor over an AC motor for garage door openers?
Usually a DC motor can be expected to deliver higher torque in a smaller size package.
What are the main advantages of using a DC To AC Converter?
The major advantages of using a DC to AC converter are that it can reduce electrical consumption. Similarly, these converters can charge many important items, such as phones and laptops.
How do you change over a ac motor to a dc generator?
Type your answer here... how can you change an ac motor to a dc generator
Which is more useful ac aor dc?
AC and DC current both have useful advantages, depending on what you what to do with it.AC is more useful for sending long distance over transmission lines, as AC can be put through a transformer to change the voltage easily.All electronic devices work using DC only. Batteries provide DC and are readily available or can be created. All electronic devices, when used on a domestic AC supply, have their power converted from AC to DC, either within the device or an external power supply.More devices use DC than AC, but we could not get the power to where it is needed without AC transmission lines. Heavy motors were more efficient when constructed for AC supplies, but these days DC stepper motors are taking over, using electronic control circuits.
What are the advantages of using a DC motor in a ceiling fan compared to a traditional AC motor?
DC motors in ceiling fans offer advantages such as energy efficiency, quieter operation, and variable speed control compared to traditional AC motors.
Why used ac over dc in train?
ac transmits the voltage over long distances. so v use ac in trains
Which current is better ac or dc?
DC is more powerful, the actual ratio is 1.732AC=DC
What are the advantages of AC and DC electricity?
AC electricity will not dissipate in charge traveling along a wire for up to hundreds of miles whereas DC dissapates at about 2 miles at its best. DC is simple and easy, the simplist electrical cirtuit possable.
